, there is a connecting body e consisting of a center link C and side links d and d' pivotally connected to both ends of the center link C.
The ends of the side links d and d' are pivotally connected to the respective installation parts b' and the center link C of the EV assembly e. The center link C moves in parallel along the axis O in the cable installation direction, and moves toward and away from the axis O.
A guide means f is provided, and an offset portion consisting of a curved shape etc. of the cable g laid across both the laying portions b1 and b' is fixed to the center link C and both side links d and d' of the connecting body e. Some cables are constructed in such a way that deformation of the offset portion due to longitudinal fluctuations of the installation location can be always controlled to a good curved state.

あるため、布設が面倒であると共にコストが高くなると
いった難点を有していた。However, in such a device, since the relative movement of the installation parts b and b' is handled by tilting the connecting body e, it is difficult to apply it to a long suspension bridge, etc., where the above-mentioned movement amount can reach about 1.5 m. If this is installed, there is a problem that the connecting body e becomes large and requires a large installation space, and the device is a link mechanism consisting of the connecting body e and the guide means f. Since the structure is complicated, installation is troublesome and costs are high.
本発明は上記従来の難点を解消し、取付スペースが小さ

移動に対応するようになっている。Next, to explain the operating state of the device configured as described above, the installation location 1 shown in the drawing has one or both installation sections 3.4 extending in the longitudinal direction of the installation location 1, which is also the longitudinal direction of the cable 22 to be installed. However, in this state, if the two laying sections 3.4 come together due to changes in load, etc., and move toward or away from each other, the laying sections 3.4
Since the support base 7.8 of the surface support base 3.8 moves in the same way, for example, if the two laying parts 3.4 are separated, the distance between the two ends of the cable 22 increases, so that the tension of the cable 22 causes the surface support base 3. 4 approaches against the force of the projectile 21,
If the cable 22 that is hung between the two cabzundrums 6.6 is pulled out and the two laying parts 3.4 are brought closer together, the distance between the two ends of the cable 220 becomes smaller.
The surface support base 3.4 is raised to a height of 11 by the elastic force of the elastic body 21.
In the meantime, the cable 22 that is close to the two cab drums 6.6 is wound up so as to correspond to the movement of the two installation parts 3.4.

A pair of relatively movable installation sections are provided which are separated by a sliding space in a direction intersecting the longitudinal direction, and supporting bases that support the capstan drum pivotably are disposed oppositely in both installation sections. The support base is fixedly installed on the installation part, and the other support base is installed on the installation part so as to be slidable in the longitudinal direction, and the surface support base is connected by a telescoping cylinder that can be expanded and contracted in the longitudinal direction. At the same time, an elastic body is attached to the extensible cylinder to apply an elastic force in the direction of extension to the cylinder, and a part of the cable laid between the capstan drums is connected to the kawaguchi. Because of this, the installation space is small, and the installation part can handle a large amount of movement, and the structure is simple, making installation easy and inexpensive, especially when the installation is subject to frequent expansion and contraction due to changes in load during vehicle traffic. Suitable for installation locations.
